I'm trying to figure out how to exclude a specific string from a url link between two characters. In this case variable test. Then end on first " character.
<a href="/?q=test¶meter1¶meter2" ...more content
So far I built this Regex expression:
(?<=[?]q=)[^"]*
Required result:
<a href="/?q=test ¶meter1¶meter2 " ...more content
Thank you!
Use look arounds to match between test and ", where test is a whole word (eg not testing) and is a query param (preceded by = or &, so order of params doesn’t matter):
(?<=[=&]test\b).*?(?=")
See live demo.
Then use your (unspecified) language/tool to replace matches with blank.
To match everything not test in params, ie other params preceding or followingtest too:
(?<=q=).*?(?=\btest\b)|(?<=[=&]test\b).*?(?=")
See live demo.
You can use
(\?q=[^&]*)&[^"]*
and replace with $1. See the regex demo and the regex graph:
Details
(\?q=[^&]*) - Capturing group 1: ?q= text and then any zer or more chars other than && - a literal & char[^"]* - zero or more chars other than a ".
